Title:
BALLAST WATER TREATMENT DEVICE, SYSTEM FOR RENDERING BALLAST WATER HARMLESS USING THE DEVICE, AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2011/108032
Kind Code:
A1
Abstract:
Provided is a ballast water treatment device capable of not only passing water therethrough but also decomposing a bactericidal component contained in ballast water, thereby enabling a great reduction in things like a bactericidal component adsorbent.
Specifically provided is a ballast water treatment device (3) configured by a shear flow generation unit (31) which is provided in an intake pipe (7) extending from an intake port (6) to a ballast tank (1) and contains one or more stepped venturi tubes (33) that are arranged side by side and receive the supply of seawater (2) taken from a high-pressure feed pump (9), and a swirling flow generation unit (37) which is provided with a main body cylindrical portion (37a) provided next to the shear flow generation unit (31) via a connection pipe (36) and a diffuser pipe (38) connected to the intake pipe (7) leading to the ballast tank (1). Said ballast water treatment device supplies the ballast water (2) to the ballast tank (1) via a bactericidal component mixing device (4).
